CAR-TRUCK.

:PEGIFICATION forming part of Letters Patent No. 495,338, dated April 11, 1893.

Application filed November 8, 1892 Serial No. 451,293. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES W. HUNT, a citizen of the United States, residing at West New Brighton, in the county of Richmond and State of New York, have invented an Improvement in Car-Trucks, of which the following is a specification.

This invention relates to the manufacture of car trucks especially those made of sheet metal, in which the side frames are stamped up with stiffening flanges, and the cross bearer or transom is received into bearings upon the side frames so as to allow the frames to turn on the ends of the cross bearer.

In the drawings, Figure 1 is an elevation of a side frame. Figs. 2, 3 and 4 are sections of the frame and partial elevations of the transom or cross bearer in some of the different forms used by me.

The side frames 0 are of any desired size, material or configuration, and the axle boxes B receive the axles, and such boxes are received in or connected to the side frames as usual. The side frames are preferably of pressed steel with flanges 2 and 3 around the edges of such side frames for the purpose of stifiening and strengthening the same, and in the center of each side frame is a circular opening for the reception of the end of the cross bearer F, which cross bearer has round ends to pass into the hearings in the centers of theside frames 0. The metal at the central hearings in the side frames may be conical, as seen in Figs. 2 and 3, or cylindrical, as seen in Fig. 4, for the reception of the ends of the cross bearer, and reinforcing flanges or rings 6 and 7, Fig. 2, can be used to sit around the ends 8 of the transom or cross bearer F, and these rings or flanges 6 and 7 are bolted or riveted to place and they serve to strengthen the side frames at the bearings and to allow the side frames to vibrate in vertical planes as the wheels of the truck pass over inequalities in the rails, there being a slight turning motion of the side frames upon the round ends 8 of the cross bearer.

If desired, the outer ring or flange 16 may be stamped up or cast with the side frameor be a separate piece, as represented in Fig. 3, so as to inclose the end of the cross bearer F and protect the same from dust, the ring 17 being removable and made in two halves if necessary. In this case the round end 8 of the cross bearer F may be either cylindrical or convex. In some instances the cylindrical end 18 of the cross bearer F, Fig. 4, may have a collar at the outer end and the flanges or rings 26 and 27 may be divided into two parts, so as to be set around the end 18 of the transom F and within the shoulders thereof, or the rings or flanges 26 and 27 may be complete and the collar 10 may be formed by a movable piece fastened on at the end of the round bearing 18 of the cross bearer F, as shown by dotted lines.

The cross bearer F maybe made in any suitable manner, but I prefer to have the same of a forging or casting having flanges or ribs 12 and 13 at the top and bottom edges of a vertical central web or plate.

In all the forms represented the bearings for the ends of the transom may be separate from the side frames and secured to them as shown, or they may be formed with the side frames themselves.

I claim as my invention- 1. The combination in a car truck frame of side frames having central bearings with a metallic cross bearer having round ends and received into central bearings in the side frames, substantially as set forth.

2. The side frames for a car truck, formed of metal plates with turned up edges orflanges, openings for the axle boxes and central bearings in each plate, a metallic cross bearer or transom having cylindrical ends and passing into the central bearings of the side frames and secured therein, substantially as set forth.

3. The combination with the metallic cenround ends of the transom, substantially as the respective parts and for allowing the side to set forth. frames to rock vertically on the ends of the 5.
